Definitions

  • the invention relates to a linen treatment device with an arrangement for determining the imbalance.
  • An arrangement for monitoring imbalance in a washing machine is already known from EP 0 539 617 A1.
  • An electric motor monitored by a speed-measuring device for example, by means of a tacho-generator in a control device especially a series motor is provided in a washing machine.
  • An imbalance sensor which records the imbalance is constructed as a microswitch which is connected in series to the speed measuring device, for example, a tacho-generator. When an impermissible imbalance is reached, the imbalance sensor interrupts the connection to the speed measuring device and the control device.
  • the arrangement has at least one sensor to measure the temperature profile of a heating device built into the sensor, wherein the temperature profile can be varied by an acceleration caused by an imbalance.
  • the temperature distribution in a medium heated by the heating device of the sensor varies as a result of an acceleration caused by an imbalance, the temperature distribution thereby varied can be measured and the intensity of the acceleration can be deduced.
  • the direction of the acceleration can also be determined if the temperature distribution in measured in two axes.
  • a washing machine design where the sensor is arranged on the soapy water container is especially suitable. It is thereby possible to achieve a very direct determination of imbalances which are exerted on the soapy water container during spin-drying of a laundry unit in the drum.
  • the sensor can be arranged on a lever connected to the soapy water container, whereby especially tumbling imbalances, i.e., imbalances in the direction of the axis of rotation of the drum, can be efficiently measured.
  • Such tumbling imbalance cannot be measured by means of a tacho-generator.
  • it can be determined by means of an arrangement according to the invention and with a corresponding alignment of the sensor element.
  • speed ramping i.e., by controlling the motor. The same applies to a washer drier.
  • the senor is arranged in a damper which damps the vibrations of the soapy water container or in a foot of the washing machine.
  • the senor is located below the upper outer surface of the linen treatment device.
  • the measuring function of the sensor is thereby made directly accessible to the user. It is advantageous if the value measured by the sensor is displayed on a display device. The magnitude of the imbalance is thereby made recognisable to the user.
  • Equally the result of a measurement made by the sensor can also be displayed for the user by a separate display device.
  • the sensor for determining imbalance can also be used to subsequently determine the mass of the linen placed in the drum in the rest state of the washing machine.
  • a warning device can also be activated by means of the sensor which gives a warning signal when the washing machine is overloaded.
  • the loading which is conventionally determined, for example, by an inductive distance measurement, can be determined in a new way compared with the prior art. The loading or the weight or the water level in a washing machine or in a dishwasher can thus be displayed.
  • the sensor can advantageously also be used to determine the levelling of any household appliance, especially a washing machine.
  • the sensor can fulfil a double function: on the one hand, it is used to determine imbalances or the mass of a laundry unit and on the other hand, it is used for levelling the washing machine.
  • the sensor is useful not only when setting up the household appliance in order to set up the household appliance for the first time so that it stands horizontally in both directions in the plane but also later to check whether the household appliance is standing horizontally on both directions as before or whether it has sunk in one or both directions. If pre-determined, still permissible deviations are exceeded, a warning signal is generated so that the user suitably re-levels the appliance.
  • the levelling is carried out by the household appliance itself.
  • servomotors are provided, preferably in the area of the appliance feet, or a pneumatic or hydraulic pressure system is provided by which means the fluid can be distributed such that the device stands horizontally in both directions.
  • the weight of the household appliance or the useful load i.e., the loading in a washing machine or a washer drier
  • the useful load can be determined indirectly by evaluating the acceleration of the sensor. Acceleration sensors are known, for example, from the company Memsic. The measurement is made as follows: the drum is first loaded, then it sinks as a result of the loading. This results in an acceleration at the sensor element. Moreover, the time is measured as the second quantity. The distance covered as a result of the loading with the washing can thus be determined. From a knowledge of the damping of the household appliance, the force brought about by loading with the linen can then be determined using Hook's law so that the imbalance mass can be determined.
  • the speed of the washing machine can be reduced and the laundry unit can be re-aligned by reversing.
  • Speed ramping can also be implemented to control the motor.
  • a particular problem with measuring imbalance involves determining the so-called tumbling imbalance, i.e., the imbalance along the axis of the drum and the drive motor. However, this can be determined according to the invention if the sensor element is suitably selected and aligned. If the measurement signal is simultaneously returned in the control loop of the machine, the tumbling imbalance can be compensated. However, the tumbling can only be determined with a biaxial sensor system.
  • FIGS. 1 a, b is a cross-section through a sensor according to the invention
  • FIG. 2 shows an arrangement equipped with the sensor from FIGS. 1 a, b for levelling a household appliance
  • FIG. 3 shows an arrangement for determining the imbalance of a drum and the loading and the level of a washing machine
  • FIG. 4 is an equivalent circuit diagram for the measuring arrangement from FIG. 3 .
  • FIG. 5 is a baking oven with sensors according to the invention.
  • FIG. 6 is a spray arm of a dishwasher with a sensor.
  • a circular plate 4 which serves as a temperature sensor is arranged on a substrate 2 , which preferably consists of silicon, above a circular hole 3 .
  • the plate 4 In its central area the plate 4 is penetrated by a rod 5 which heats up, so that a thermal profile builds up above the rod 5 in a space 6 which has a decreasing temperature T with increasing distance from the rod 5 .
  • Above the rod 5 forms a substantially spherical or conical area 7 of especially strongly heated gas.
  • the temperature T inside the space 6 is plotted as a function of the distance from the rod 5 in FIG. 1 b.
  • the temperature T decreases substantially proportionately with increasing distance from the rod 5 .
  • the gas molecules or gas atoms in the space 6 above the rod 5 are accelerated towards said rod and the plate 4 so that the position of the thermal profile with respect to the original position changes. Since sensors for the temperature measurement are built in the plate 4 preferably in pixel fashion, this positional change can be measured as a change in temperature in one of the two directions X and Y extending through the plane of the plate 4 . In this case, not only the positional change of the profile itself can be measured but also its time profile since the sensors inside the plate 4 determine when the profile has changed.
  • a thermal profile 7 not completely symmetrical with respect to the rod 5 builds up if the rod 5 is not arranged completely vertically.
  • This can be used to adjust the levelling of a household appliance.
  • either a plurality of sensors are present in the fashion shown in FIG. 1 a or there is only one sensor in one of the corners of the household appliance on its upper surface, i.e., the working surface.
  • a display 8 ( FIG. 2 ) where a centring cross 9 indicates when the position of the household appliance is completely levelled.
  • a variable circular display 10 must cover the centre point of the cross 9 with its centre point.
  • the feet of the household appliance must be adjusted in height, as shown in FIG. 2 , for which the user receives instruction from the information on the display.
  • the feet which need to be adjusted are shown by the displays 11 , 12 , 13 .
  • any household appliance especially a linen treatment device such as a washing machine or a washer drier can be levelled.
  • the levelling information can also be evaluated by the appliance control system. During the initial setting up of the household appliance at a location the at least one sensor or the plurality of sensors controls the levelling. If this is not correct, the height adjustment of the adjusting feet is automatically varied by means of servomotors or by means of a hydraulic or pneumatic system.
  • the levelling information is either displayed visually, as by the display 8 , or it is passed on audibly to the user by means of a loudspeaker.
  • the household appliance preferably has an interface for connecting the household appliance to the internet or online assistance for the adjustment is given to the user by telephone.
  • a sensor 14 is arranged below a soapy water container (shown only schematically here).
  • the soapy water container 15 is mounted in a household appliance 20 (not reproduced to scale here) using tension springs 16 , 17 and dampers 18 , 19 .
  • a laundry unit 21 acts with the force of its weight together with the weight of the soapy water container 15 on the dampers 18 , 19 .
  • a sensor 22 can also be provided which is mounted on a rail 23 which is connected via a hinge joint 24 to a lever arm 25 of a lever 27 which is pivotable about a fulcrum 26 .
  • the other lever arm 28 of the lever 27 is connected to the soapy water container 15 parallel to the direction of the axis of rotation of the soapy water container 15 .
  • a rotational movement of the lever 27 is converted to a translational movement in the direction of a path b via the hinge joint 24 . If the soapy water container 15 is accelerated downwards as a result of an imbalance or by the loading with washing having a force F, the force of its weight, this acceleration is converted via the lever 27 into a horizontal acceleration a along the path b.
  • M is the weight of the total load and g is the acceleration due to gravity.
  • tan ⁇ (see FIG. 4 ) is given by:
  • the sensor 22 is capable of measuring the acceleration values.
  • the acceleration values can then be used to determine both the mass of the washing and any imbalance of the drum during operation.
  • the sensor 22 is suitable both for static and for dynamic measurements.
  • the pressure inside the sensor can also be varied by applying a force.
  • the change in pressure then results in a change in temperature which is detected by the temperature sensors built in the plate 4 . From this it is then possible to calculate a force from which the mass either of the laundry unit or an imbalance can be deduced.
  • the temperature sensors it is furthermore possible to deduce accelerations in the sensor plane and any change in angle, as already shown above with reference to levelling in connection with FIG. 2 .
  • the quantities weighing, levelling and imbalance monitoring can be determined using a sensor such as shown in FIG. 1 a.
  • the sensor is either attached to the soapy water container so that it serves for levelling and imbalance monitoring or it is arranged on the frame structure of the household appliance so that, in addition to weighing and monitoring imbalance, it can also be used for levelling the household appliance.
  • the user is assisted in adjusting the household appliance when this is first set up in a position.
  • the customer is also assisted in loading the household appliance in that he is notified about the washing already inserted, for example, via a display or audibly.
  • a warning signal is generated so that any damage to the household appliance caused by the mass of a laundry unit being too high is avoided.
  • Tumbling imbalance i.e., an imbalance along the drum motor axis of the washing machine or the washer drier can also be identified according to the invention so that measures to compensate for the tumbling imbalance can be introduced.
  • the tumbling imbalance can be compensated by speed ramping using a suitably matched motor control system. If an imbalance has been identified, a regulating mechanism results in countercontrol, for example, by reversing the laundry unit.
  • a sensor 30 preferably a second sensor 31 , is provided, said sensor being affixed below a sheet-metal guide frame 32 of a baking oven 33 .
  • both sensors 30 , 31 are based on measuring a temperature profile produced by a heating device built into each sensor 30 , 31 .
  • the sheet-metal guide frame 32 receives baking sheets in guide strips 34 .
  • the sheet-metal guide frame 32 is suspended by means of springs 35 to 38 inside a frame of a baking oven 33 . When the baking oven 33 is loaded, the springs 35 to 38 are deflected and the sheet-metal guide frame 32 is thus lowered.
  • the sensors 30 , 31 are thereby accelerated in the perpendicular direction.
  • the perpendicular movement of the sheet-metal guide frame 32 is converted into a horizontal movement in order to accelerate the sensors in the horizontal direction in this fashion. In this way the loading of the baking oven 33 with baking goods is measured.
  • the considerable lack of sensitivity to temperature of the sensors 30 , 31 should be seen as a particular advantage of this weighing device.
  • at least two sensors 30 , 31 are provided, which for example, viewed in the sliding direction of the baking sheets, have a certain spatial offset to one another, a spatial resolution of the weight loading of the baking sheet can also be determined.
  • the air circulation during circulating-air operation in the baking oven 33 or the temperature guidance in the baking oven 33 can then be adapted accordingly.
  • the sheet-metal guide frame is easily tiltable without jamming. It can be removed for cleaning.
  • the sheet-metal guide frame 32 either consists of a wire framework or of a flat enamel frame.
  • a sensor 40 according to the invention is provided in a spray arm 41 of a dishwasher.
  • the spray arm 41 is mounted on a pivot 42 . It turns in the direction of the arrow A to spray washing solution onto the crockery.
  • the sensor 40 experiences a radial acceleration from which the rotation speed and thus the number of revolutions, the spray arm position and also any stopping of the spray arm can be determined.
  • the signal is transmitted either by radio, by pressure contact or via a sliding contact 43 which is arranged in the vicinity of the pivot 42 and produces an electrical connection with an electrical lead in the casing of the dishwasher.
  • An acceleration sensor is provided for a household appliance 20 which is used both for levelling the household appliance and also for weighing a material inserted in the household appliance, for example a laundry unit or crockery and in addition, especially for a linen treatment device, serves to monitor imbalances.
  • the sensor is based on the fact that a temperature profile produced by a thermal source, for example, an immersion heater 5 inside a sealed chamber 6 containing a gas, undergoes a displacement as a result of the acceleration which is measured by means of temperature sensors arranged in a flat plate 4 .
